Abstract:
The antitragicus muscle arises from the outer part of the antitragicus cartilage, and inserts into the helical tail and antihelix. Overdevelopment or malpositioning of the antitragicus muscle exerts an anterior pull on the helical tail, and it can cause prominent lobules. We attempted prominent lobule correction using antitragicus muscle resection and helical tail setback in combination with a Mustarde or Furnas suture technique. Seventeen children with prominent lobules underwent this technique, and all had satisfactory outcomes. Resection of the antitragicus muscle is minimally invasive and easy to perform. This procedure is a key to successful lobular setback.
